'Best friends' at the wedding??

My fiance and I are getting married in June. Obviously I want my closest friends there as well as family.

Well, to give some back story. My 'first' best friend and I met in 6th grade. That was about 11 years ago. I met the 'second' best friend when 'first' bf went to military school our 10th grade year, about 7 years ago. They didnt really know each other besides what they heard around school. Anyway, 12th grade came around and 'second' best friend has a boyfriend she says she loves. But she cheats on him a lot while he's at basic training. He finds out and leaves her. About 6 months later he met 'first' best friend. Now remember, these girls dont know each other enough to know 'second' best friend was with him first. Obviously she found out after awhile and does not like this girl one bit for the way she treated her now husband when he was in Basic. 'Second' bf doesn't care either way. She knows 'first' bf is very important to me and wouldn't try to put me against her. 'First' bf knows I'm friends with 'second' bf and isn't mad cause she knows she can't control who I'm friends with but doesn't like to hear about her. 'First' bf moved out of state with her husband to be on a base and hasn't lived here in 3 years but we still video chat, call and text each other about every other day. So, I've been getting closer to 'second' bf because she lives closer to me.

Anyway, I need some advice here. I want them both at my wedding. I'm not doing bridesmaids for several reasons but this is one of them cause I would want them both up there with me. I'm not sure if 'first' bf knows I'm still close with 'second' bf because I dont talk to them about each other but 'second' bf doesn't mind 'first' bf being around. I didn't think about how kind of awkward it would be for my 2 best friends to be around each other at my wedding until now.. how do I tell 'first' bf that 'second' bf is gonna be there, or should I? I feel like if I do, she won't come. But I also dont want her to come and have that hot face, heart pounding, pissed off feeling, seeing her there. Ik that feeling and definitely don't want to make my oldest bf feel that way. I also don't want her to think I'm choosing 'second' bf over her by inviting her too knowing she might not come if she's there.. please give me some advice. I am at a loss. I love both these girls like sisters but I dont wanna make them feel uncomfortable.

Note: I dont wanna hear, it's your wedding they'll get over it. At MY wedding I want my friends to be comfortable being there. If they're uncomfortable, I will be too.
